CHARLES T. RICHMOND, OF CLEVELAND, OHIO, ASSIGNOR TO THE NATIONAL CARBON COMPANY, OF TRENTON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

BATTERY-FILLING MACHINE.

To all whom it may concern:

Be it known that "I, CHARLES T. Bron- MOND, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Battery-Filling Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of this invention is to provide a simple and efficient mechanism for making dry batteries, particularly such small batteries as are used for pocket electric lights and similar purposes. The essential characteristics of the machine are hereinafter more fully described and summarized in the claims.

In the drawings Figure 1 is a side elevation of the machine. Fig. 2, is a horizontal section on the line 2-2 of Fig. 1. Fig. 3 is a front elevation. Figs. 4 and 5 are horizontal sections on the correspondingly numbered lines of Fig. 3. Figs. 6 and 7 are respectively aplan and a vertical section of the holder for the batterycups. Fig. 8 is a side elevation of the plunger for packing the filling. Fig. 9 is a side elevation of the holder for the carbon rods. Figs. 10, 11 and 12 are views of the battery,Fig. 10 showing the cups with its paper lining; Fig. 11, the calrlbon electrode, and Fig. 12, the complete ce Referring to the parts by letters, A represents a suitable frame which has on its forward side guides a for a suitable crosshead B and on its upper end journal boxes a for a main driving shaft C. -A crank c on this shaft is connected by a pitman D with the crosshead. Removably clamped to the cross head is the shank e of the spring chuck E, in which the plunger F is held by means of the clamping ring e engaging and compressing the tapered exterior of the chuck.

Loosely journaled on the shaft C is a belt pulley G, and a suitable clutch is provided for coupling this when desired with the shaft. This clutch may consist of a bolt h occupying a recess in the collar H, which is rigid with the shaft, the bolt being pressed toward the pulley G by a spring it. There is a recess gin the side of the pulley hub which Specification of Letters Patent.

this bolt is adapted to enter, thereby locking the two together. Occupying a circumferential groove h on the collar H is a yokepiece J which is ressed upward by a spring 7' and has a poin ed u per end adapted to normally engage an inc ined projection of the bolt h and prevent the same looking with the pulley G. When the yoke J is drawn down however, as it may be by a treadle (not shown) connected by the lower end of the rod 7' the bolt is pressed towards the pulley and as the notch in the latter comes opposite the bolt, the bolt springs into thenotch, and the shaft C is thus caused to rotate and reciprocates the lunger until the pressure is removed from t 1e treadle.

K represents the cu holder which may be a long block of wood raving vertical holes 7c in it, each adapted to receive one of the Zinc cups. Surmounting the holder K is a plate K havin holes 7c adapted to register with the holes and having dowel points k to preserve such registration. After the cups X with their paper lining Y, have been placed in the holder K, the plate K is put in place and the holes is are filled with suitable battery filling preparation. Then the member L having projecting pins Z of a diameter smaller than the cups, is placed over the plate K and forced downward forcing the material in the holes in into the cups and giving it a preliminary packing. Then the holder with the surmounting plate K is laced beneath the plunger F. 011 the rear si e of the holder are a series of notches k Secured to the forward legs of the machine is the flat cross bar a? having on it an inclined projection a so positioned that when one of the notches k engages it, the plunger F is directly over one of the holes it. At the beginning of the operation, the holder is placed with its first notch k in engagement with the projection a and the treadle is depressed, allowing the plunger to descend into the first hole It" k, packing the material in the cup. Then as the plunger recedes and clears the holder, the latter is shoved lengthwise one tooth so that the plunger on its next descent enters the next hole. This operation is continued until all the cups have been packed.

By having the projection a and the notches k beveled on one face as shown, it is easy for the holder to be fed longitudinally and brought accurately into position for each operation. As the plunger recedes, the holder being drawn slightly forward, is then shoved to the left, a distance something less than the distance between consecutive notches, and then by being shoved rearward the incline of the projection a engages the incline of the notch 1c, and the lengthwise and rearward pressure results in the holder being brought accurately into place.

After the cups have been .packed, the member N shown in Fig. 9, consisting of a bar with a series of depending tubular nipples n, is brought into action. In the bore n of each nipple is placed the carbon Z for the battery, which, as shown, may have a brass cap 2, and be pointed at its end 2. This holder with the carbons in place, is put on top of the plate K, with the nipples depending into the openings 70. Then a plunger adapted to enter the bore n is substituted for the plunger F (or the holder is passed onto a similar machine with a smaller plunger) and this plunger descends successively through the difierent bores n forcing the carbon down into the material in the cup, thereby completing the operation and producing the bat tery shown in Fig. 12, wherein X represents the zinc cup, Y the paper lining, Z the carbon element, and IV the battery filler.

By the above described machine, the cups are filled rapidly and regularly. The right amount of the filling material is supplied to the cell and it is packed with the desired pressure. The inserting of the pointed carbon by pressure into the mixture is a simple and efficient operation and insures a close contact between the carbon and mixture as well as adding to the tight packing of the latter.

Having thus described my invention, I claim:

In a battery filling machine, the combination of a holder for the cup, a surmounting holder for a substance to enter the cup, a plunger to force the substance into the cup said holder for the substance being positioned relative to the holder for the cup so that the substance forced into the cup is guided by the holder therefor until it enters the cup.
